Between one scare and another due to the new variants that emerge, the activities of Anvisa (National Health Surveillance Agency) and its specialized technical guidelines for government decisions related to the pandemic by Covid-19 continue to stand out.
On its website are the most reliable information about the pandemic and the variants of the new coronavirus.
Regarding the most recent variant, called omicron by the WHO (World Health Organization), and the vaccines used, Anvisa highlights that it has no knowledge, so far, of potential impact.
The agency discloses that the current vaccines from Pfizer, Butantan, Fiocruz and Janssen laboratories remain effective in preventing Covid-19.
And he recommends that the best thing people can do is vaccination and boosting the immunizing agent. It is also important to maintain protective measures: mask, hand washing and social distance.
The first warning about the omicron came quickly from South Africa, but scientists still don’t know where in the world the variant emerged.
The omicron with its 32 mutations inside it causes concerns because, like previous variants, they may or may not be related to increased transmissibility and circumventing the protection provided by vaccination.
Some variants have really spread around the world, like delta, but others, like beta and gamma, never seem to have gone far beyond the regions where they arose.
